From Glucose and Ketones to Genetics and Toxins—Why Testing Beats Guessing in Cancer Prevention and Metabolic Therapy

Written and researched by Keith Bishop, Clinical Nutritionist, Cancer Coach, Retired Pharmacist, and founder of Prevail Over Cancer

What if the most dangerous cancer risks aren’t visible on a scan or felt in the body—but quietly building in your blood, urine, and genes?

In cancer care, guessing is gambling. Symptoms can be vague, and even “clean” imaging doesn’t mean the terrain is safe. That’s why lab testing isn’t just helpful—it’s essential. From glucose and ketones to hormone metabolites and heavy metals, these biomarkers reveal the biochemical landscape cancer cells exploit—and the ones we can disrupt.

Whether you're navigating active treatment, remission, or prevention, here’s a breakdown of the tests I recommend most often for clients—and why they matter.

The following tests are part of what I help clients with and are not a comprehensive list. It is essenti...

Improving Your Natural Killer (NK) Cell Function:
Your Immune System's Frontline Warriors Against Cancer

Researched and written by Keith Bishop, Clinical Nutritionist, Cancer Coach, Retired Pharmacist, and founder of Prevail Over Cancer.

Natural Killer (NK) cells are a vital component of our innate immune system, acting as the body's first line of defense against cancerous and virally infected cells.[i] Unlike other immune cells, NK cells can recognize and eliminate abnormal cells without prior sensitization, making them crucial in the early detection and control of tumors.[ii]

Natural Killer (NK) cells are a special kind of white blood cell that belongs to a group called lymphocytes, which help defend your body. They make up about 5–15% of your lymphocytes in the bloodstream[iii]. Unlike other immune cells like T cells and B cells, which need to “learn” what to attack, NK cells are part of your body’s fast-acting, built-in defense system. They can quickly recognize and attack vi...

Researched and written by Keith Bishop, Clinical Nutritionist, Cancer Coach, Retired Pharmacist and Founder of Prevail Over Cancer.

As cancer rates continue to rise across the U.S., especially in agricultural states like Iowa, many are asking: could the food we eat—and how it’s grown—be part of the problem?

🚜 Conventional Produce and Pesticide Exposure

Conventional fruits and vegetables are often grown with synthetic pesticides and herbicides, including glyphosate, malathion, and chlorpyrifos—chemicals classified as probable or possible human carcinogens by the International Agency for Research on Cancer (IARC). While regulatory agencies like the EPA set limits on residue levels, recent studies suggest that even low-level, chronic exposure may contribute to cancer risk.

📍 Who’s Most at Risk?

• Farmworkers and pesticide applicat...

From Monastery Remedy to Modern Research: How Monk Fruit Is Sweetening the Fight Against Cancer

Researched and written by Keith Bishop, Clinical Nutritionist, Cancer Coach, Retired Pharmacist, and Founder of Prevail Over Cancer

The Sweet Origin Story of Monk Fruit

Monk fruit, also known as Luo Han Guo, comes from a vine native to China’s Guangxi province. Buddhist monks first cultivated it over 200 years ago to sweeten herbal brews and soothe coughs. The fruit owes its intense sweetness to mogrosides—triterpene glycosides 200–350 times sweeter than sucrose—and is recognized as safe by the FDA.[1]

How Monk Fruit Keeps Blood Sugar in Check

Early animal studies indicate that mogroside-rich extracts may help lower fasting blood glucose levels, enhance insulin secretion, and reduce oxidative stress in diabetic mice.[2]

Human trials echo these benefits: participants consuming monk fruit extract experienced 10–18% smaller post-meal glucose spikes and 12–22% lower insulin responses...

Dandelions may be the most underestimated plant in your backyard. While often dismissed as weeds, their roots have been studied for surprising anticancer properties. Let’s delve into what the research reveals, how to use dandelion root safely, and what to be aware of if you're undergoing cancer treatment.

Anticancer Actions of Dandelion Root

Dandelion root extract (DRE) contains bioactive compouP%$nds like taraxasterol, chlorogenic acid, luteolin, and sesquiterpene lactones. These compounds have shown the ability to:

• Trigger apoptosis (programmed cell death) in cancer cells without harming healthy ones[i]
• Suppress metastasis by downregulating matrix metalloproteinases (MMP-2 and MMP-9) while supporting P53 expression.[ii]
• Increased P53 is often called the “guardian of the genome”. It is a tumor suppressor protein that plays a significant role in cancer development. When activated, it helps:[iii] [iv]
• Cell Cycle Arrest: p53 halts cell division at checkpoints (especially G1/S

Introduction: What is Red Light Therapy?

Red light therapy (RLT), also known as Photobiomodulation (PBM), is a non-invasive treatment that uses low-wavelength red light or near-infrared light to stimulate cellular function. It’s gaining traction for its potential to support skin health, reduce inflammation, and promote tissue repair.

RLT targets the mitochondria, the energy-producing centers of cells. When exposed to specific wavelengths (typically 600–850 nm), mitochondria absorb the light, stimulate mitochondrial cytochrome c oxidase, and produce more ATP (adenosine triphosphate)—the energy currency of the cell. This boost in cellular energy helps enhance healing, reduce oxidative stress, and decrease inflammation.[i]

Red Light Therapy and Other Health Issues

Beyond its cosmetic applications, RLT has been studied for its effects on several health issues, including:

• S...
